Chapter no 30

Project Hail Mary

‌Iﬁnish oﬀ the last bite of my meburger and gulp down the vitamin- enriched soda. I put my dishes in the sink and check the clock on my kitchen wall. Wow, is it VℓIλλ already? I better hurry up.‌

My ﬁrst few years on Erid were touch-and-go. Taumoeba kept me alive, but I became severely malnourished. The microbes gave me calories, but they weren’t a balanced diet.

Those were painful days. I had scurvy, beriberi, and a raft of other maladies. Was it worth it? I still don’t know. I might never know. There’s no way to communicate with Earth. It’s sixteen light-years away.

For all I know, the beetles may have malfunctioned or missed their target. I don’t even know if the climatologists like Leclerc were right in their models for what would happen. The Hail Mary might have been hopeless from the get-go. Earth might already be a frozen wasteland with billions of corpses.

But I try to stay positive. What else have I got?

For what it’s worth, the Eridians are fantastic hosts. They don’t have a government, per se, but all the important entities agreed to do whatever it takes to keep me alive. After all, I played a critical role in saving their planet. And even if I hadn’t, I’m a living, breathing alien. Of course they’re going to keep me alive. I’m of extreme scientiﬁc interest.

I live in a big dome in the middle of one of their “cities.” Though “city” isn’t quite the right word. A better description might be a “cluster.”

I have grounds and everything. Thirty Eridians outside the dome maintain my life-support systems, or so I’m told. And my dome is very close to one of the larger science centers. Many of Erid’s greatest minds collect there and thrum. That’s sort of a song and discussion in one. But everyone talks at the same time and it’s not really conscious on their part. Somehow the thrum

leads to conclusions and decisions. The thrum itself is much smarter than any Eridian in it. In a way, Eridians can become ad-hoc neurons in a group mind. But they come and go as they please.

I’m particularly interesting, so pretty much every scientist on the planet came together to thrum up ways to keep me alive. I’m told it was the second- largest science-oriented thrum ever executed. (The largest, of course, was when they had to make a plan for dealing with Astrophage.)

Thanks to my Earth scientiﬁc journals, they know all my nutritional needs and how to synthesize the various vitamins in labs. Once they solved that, smaller, less-focused groups worked on making them taste better. That’s more or less up to me, actually. Lots of taste tests. Glucose, common to both Eridian and Human biomes, comes up a lot.

The best thing, though, is they managed to clone my muscle tissue and grow it in labs. I can thank Earth science for that. They were nowhere near that technology when I ﬁrst showed up. But that was sixteen years ago— they’re catching up quite well.

Anyway, it means I can ﬁnally eat meat. Yes, that’s right, I’m eating human meat. But it’s my own meat, and I don’t feel bad about it. Spend a decade eating nothing but odd-tasting, vaguely sweet vitamin shakes and then see if you’ll turn down a burger.

I love meburgers. I eat one every day.

I grab my cane and head out. I’m not a young man anymore, and the high gravity of Erid has only made my bones degenerate faster. I think I’m ﬁfty- three years old now, but I’m not sure. I’ve done a lot of time-dilated travel. I can accurately say seventy-one years have gone by on Earth since I was born, for what it’s worth.

I leave through my front door and cross the grounds. There are no plants or anything—I’m the only thing on this planet that can survive my environment. But there are some very tasteful and aesthetically pleasing rocks. It’s become a hobby of mine: making the grounds as pretty as possible. The Eridians just see a bunch of rocks, but I see all the colors.

They installed lights at the top of the dome that get brighter and dimmer on a twenty-four-hour cycle. I explained that’s critical to my mood and they

took my word for it. Though I did have to explain to this species of interstellar travelers how to make lightbulbs.

I make my way along the gravel pathway to one of the many “meeting” rooms at the dome’s wall. Eridians value face-to-carapace communication as much as humans do, and this is a good compromise. My side is within my bubble environment. And on the other side of the 1-centimeter clear xenonite is a room that’s out in Erid’s natural atmosphere.

I hobble in. It’s one of the smaller meeting rooms, really only suitable for a one-on-one conversation. But it’s become our go-to spot for meeting up.

Rocky waits for me on the Eridian side. “Finally! I’ve been waiting for ℓλ minutes! What took you so long?!”

I can understand Eridian ﬂuently now, of course. And Rocky is equally ﬂuent in English comprehension.

“I’m old. Give me a break. It takes me a while to get ready in the morning.”

“Oh, you had to eat, right?” Rocky says, a tinge of disgust in his voice. “You told me not to talk about that in polite company.”

“I’m not polite company, my friend!” I snicker. “So what’s up?”

He wiggles and jiggles. I’ve almost never seen him this excited. “I just heard from the Astronomy hive. They have news!”

I hold my breath. “Sol? Is it about Sol?!”

“Yes!” he squeals. “Your star has returned to full luminance!” I gasp. “Are you sure? Like, Iℓℓ percent certainty?”

“Yes. The data was analyzed by a thrum of λV astronomers. It checks out.” I can’t move. I can barely breathe. I start to tremble.

It’s over. We won.

Simple as that.

Sol—Earth’s sun—has returned to its pre-Astrophage brightness. There’s only one possible way that happens: Astrophage is gone. Or at least reduced in population so much that it doesn’t matter.

We won. We did it!

Rocky cocks his carapace. “Hey, your face is leaking! I haven’t seen that in a long-ass time! Remind me—does that mean you’re happy or sad? ’Cause it can mean either one, right?”

“I’m happy, of course!” I sob.

“Yeah, I thought so. Just checking.” He holds a balled claw against the xenonite. “Is this a ﬁst-bump situation?”

I press my knuckles to the xenonite as well. “This is a monumentally epic ﬁst-bump situation.”

“I guess your scientists got right on it,” he says. “If you account for the time it took your beetles to get there and the travel time for light to get from Sol to Erid…I think it took less than one of your years to get it done.”

I nod. It’s still sinking in.

“So will you go home now? Or will you stay?”

The…entities…that make major decisions for Erid long ago oﬀered to refuel the Hail Mary. It’s still sitting in a nice, stable orbit around Erid, where it’s been since Rocky and I ﬁrst arrived all those years ago.

The Eridians could stock it up with food and supplies, help me make sure everything is working right, and send me on my way. But so far I haven’t taken them up on it. It’s a long, lonely journey, and until a minute ago I didn’t even know if Earth was still habitable. Erid may not be where I’m from, but at least I have friends here.

“I…I don’t know. I’m getting old and the trip is long.”

“Speaking from a selﬁsh perspective, I hope you stay. But that’s just me.” “Rocky…that news about Sol…it…it makes my whole life have meaning.

You know? I still can’t…I can’t…” I start sobbing again.

“Yeah, I know. That’s why I wanted to be the one to tell you.”

I check my watch. (Yes, the Eridians made me a wristwatch. They make anything I ask for. I try not to abuse it.) “I have to go. I’m late. But… Rocky…”

“I know,” he says, tilting his carapace in what I’ve come to realize is a smile. “I know. We’ll talk more about it later. I have to get home anyway.

Adrian is going to sleep soon, so I have to be there to watch.”

We both head toward our respective exits, but he pauses. “Hey, Grace. Do you ever wonder? About other life out there?”

I lean on my cane. “Sure, all the time.”

He walks back in. “I keep thinking about it. The theories are pretty hard to dispute. Some ancestor of Astrophage seeded Earth and Erid with life billions of years ago.”

“Yeah,” I say. “And I know where you’re going with this.” “Do you?”

“Yeah.” I shift my weight from one leg to the other. Arthritis is starting to

settle in my joints. High gravity isn’t great for humans. “There are fewer than ﬁfty stars as close to Tau Ceti as we are. But two of them ended up with life. It means life—at least, the life Tau Ceti puts out—might be a lot more common in our galaxy than we think.”

“Think we’ll ﬁnd more of them? Intelligent species?”

“Who knows?” I say. “You and I found each other. That’s something.” “Yeah,” he says. “It really is something. Go do your job, old man.” “Later, Rocky.”

“Later!”

I hobble out of the room and make my way along the perimeter of the dome. They made the whole thing out of clear xenonite because they thought that’s what I would want. But it doesn’t matter. It’s pitch-dark outside all the time. Sure, I can shine a ﬂashlight out there and occasionally see an Eridian going about his business. But I don’t get sweeping vistas of mountains or anything. Just inky blackness.

My smile fades a little.

How bad did it get back on Earth? Did they work together to survive? Or did millions die in wars and famine?

They were able to collect the beetles, read my information, and implement a solution. A solution that would have involved a probe going to Venus. So there’s deﬁnitely some advanced infrastructure still there.

I bet they did work together. Maybe it’s just the childish optimist in me, but humanity can be pretty impressive when we put our minds to it. After all,

everyone worked together to build the Hail Mary. That was no easy feat.

I hold my head up high. Maybe I will go home someday. Maybe I’ll ﬁnd out for sure.

But not right now. Right now, I’ve got work to do.

I continue along the path to the large double doors leading to another meeting space. And I have to say, it’s my favorite one.

I step into the chamber. About one-ﬁfth of the room is my Earth environment. The other side of the divider wall has thirty little Eridians bouncing around like idiots. Each one is no more than thirty Earth years old. The selection process for which ones get to attend…well…again, Eridian culture is complicated.

An Earthlike organ keyboard sits in the center of my area, oriented such that the operator faces the kids. The organ has quite a few more options than a typical keyboard found on Earth. I can apply inﬂection, tone, mood, and all the other little intricacies of spoken language. I settle into the comfortable chair, crack my knuckles, and start the class.

“All right, all right,” I play. “Everyone settle down and get in your seats.”

They scamper to their assigned desks and sit quietly, ready for the lesson to begin.

“Who here can tell me the speed of light?” Twelve kids raise their claws.
